Modular Assembly

CONSISTENT AND FLEXIBLE

Consistent engineering design and efficient modular assembly allows maximum operational flexibility to be achieved. Double acting, spring fail close /open or manual override operations are combinations that are readily obtainable on the low pressure air, high pressure gas or hydraulic products. This maintains product consistency throughout any project requirement, regardless of valve size, class, actuator supply medium, pressure or actuator function (DA / SR) requirements. As a result, all products can be safely and confidently operated by personnel. In addition, the consistent design provides for a significant reduction in the quantity of recommended spare parts and seal kits, which minimizes costs within maintenance programs.
